Subject: [PATCH AUTOSEL 4.14 7/7] xen/netback: use same error messages for same errors

From: Juergen Gross <jgross@...e.com>

[ Upstream commit 2eca98e5b24d01c02b46c67be05a5f98cc9789b1 ]

Issue the same error message in case an illegal page boundary crossing
has been detected in both cases where this is tested.
